Abstract

The importance of creating specialized production sites to meet the needs of shipbuilding and ship repair enterprises of Azerbaijan in metal billets is substantiated. Technical, technological and organizational measures for the specialization of the existing production sites of Baku Steel Company LLC for the production of shipbuilding steels are recommended. The ways of mastering the production of continuously cast billets and sheet-rolling technologies from shipbuilding steels are shown.For this purpose, the need to install a continuous casting machine (CCM) in Baku Steel Company LLC is substantiated and the advantages of manufacturing steel billets on this machine are shown. It is determined that in order to reduce the overall dimensions of the caster, its radius of curvature should be 10.2 m. It is shown that the rational value of the radius of curvature reduces the probability of defects on the blanks during crystallization and makes it possible to obtain blanks of various profiles.It is shown that the combined use of EMF and hydrocarbons can reduce the defects of blanks by 2-3 times, increase the zones of equiaxial crystals by 50-80%, significantly reduce axial porosity and liquation, increase the casting speed of liquid steel by 20-30% and reduce the metal consumption of equipment by 2 times. The introduction of technologies for electromagnetic mixing and vacuuming of liquid steel makes it possible to expand the production of alloy steels for the needs of shipbuilding and ship repair enterprises.
